To all whom it 'may concern: l' Be it known that l, Vieron llt. Harmen,

citizen of the Republic of France, residing" Detroit, county of l/layne, State of ll/lichigen, have invented a. certain new and useful lmprovement in Carbureters, and declare the following to be a lull, clear', and exact description of the same, such as will enable others skilled in. the art'to which it pertains to makeanol' use the same, reference being had to the accompanying drawings, which. torni a part or" this specilication. vthis invention relates to improvements in carburetor nozzles, and has :for its object the provision of a. simple, eflective and cheap method et constructing, lthe same. lt is capable et embodiment in any oneofv several different types of carbureters as"such, with modifications in detailfeatures only; its advantages in the several respects suggested will appear :further from the description.

ln the drawings: l ,liigure l a sectional elevationl `et nozzle carbureter.

lfig. El is a similar View ,olf my improved construction applied to a compound nozzle carloureter.

.et represents a carbureter Wall provided with. an outletaperture B, through which' there engages a tube (3,' preferably ot brass and provided with a terminal collar or l'langge l). abl of hard material having an opening F for the passage ot gasolene. This disk is wrapped in an envelop or cushion G oi' relatively sol't material, preferably copper, so made to'engage over the edge and the adjacent peripheral portion of cach face of the disk; this wrapping may, if desired, have a cylindrical projection or collar ll, whose function is the centering of the disk and its envelop with respect to the axis of the tube C and of the holding nut J, into Whose hollow center portion it projects g` the holding nut, whether the collar H is einployed or not, engages with its screw threaded periphery in the complementary screw threading on the inner face of the carbureter shell. lily means oi' this holding nut the disk li and ils relatively soft envelop are forced against the Harige D oir'y the tube l), which may it desired, be spaced from the adjacentl carbureter Wall, the edges of Whose aperture ll it overlaps, by the 'Washer ll.. l do not i y @reclamation or renew rennt.

mi. construction as applied to a plain,'jsi ngle-' n zle vprojecting integrally from the carbureter Wall, 'Whose manulacture was a very' lll is a disk or washer, prefer- Patented Felnd,

confine yunysell2 to theA form oit envelop for cushion member shown in the drawings, however, although for reasons of economy el manufacture ll prefer it to an vsuinular" cushion of solder applied to one face of the disk near its edge, and adaptedto be flattened by pressure of the nutV forcing it against the shoulder in the carburetor shell, or some such Similar equivalent. The single gasolene channel, in the form of device illustrated iin Fig. l, is shown at la; and below .the holding nut Jthough somewhat spaced therefrom, is the t readed plug M, by Whose removal access is afforded to the parts already descriloed. l

With a construction of this character ll am enabled to lhave the wallet lthe nozzle proper made 'very thin, thus 'making' a reduction in its diameter possible, and inrturn 4brfufitging the action ol the aspirating' air current about the *nozzlejso much closer -to the vacuum-drawn stream of gasolene |enfilerging from the top of the nozzle. l am furthermore enabled to dispense with a nozexpensive item, both as regards actual mass ofmaterial used and the expensive and delicate drilling of a bore through the projecting vblank ol metal.

' 'Ill' substitution of one disk or washer for an- 95 other, the holding nut J with its large central. orifice remaining unchanged, and being' easily removable when the disk is to loe changed. A tight lit is assured because of the screwing up of the holding nut .l against the relatively soft envelop G to the desired degree of tightness against the flange B olf the tube A. 4

Fig. 2 shows' the application or this idea.

to a compound nozzle carbureter, in which y two gasolene feeds are delivered to concen-l tric nozzles ch as shown in the patent to Bavel-cy, No. 997,953. In this forni the carhureter wall is provided with two gasolene outlets N and l?, one being in direct connecsgg nasales tion with the supply channel L from the lloat chamber, the other being broken by an at* mospherie air well I, to effect compensation and uniformity of mixture at varying engine speeds, now well known in the art. rl`he two nozzle tubes Q and R are arranged one within the other, the lower end of the inner tube R resting in and passing through the centrally bored and peripherally threaded nut O, which adjustably engages in a complementar-ily threaded portion of the inner face of the carburetor wall A. Nut O which supports the outer tube Q is provided with a hole T by which it is placed in direct communication with the atmospherieallj` exposed gasoleue channel P, and the tube Q is preferably, though not necessarily, flanged at its lower end, a washer Sbeing preferably interposed between the flange and the overengaging portion of the shell at the top of the bored passa gein which the threaded nut O engages. lust beneath the lower end of the threaded nut. O, though appreciably spaced therefrom'is a perforated disk lil" with its envelop lV, similar to the disk E and its envelop G shown in Fig. l, which preferably rests againsa'seat on shoulder ll in the carbureter shell. and is adapted to be held in position with the required degree of firmness by means' ol the threaded and centrally apertured holding nut Z, similar to the holding nut J in the construction shown in Fig. l. The well l' receives its fuel through a similar removable disk member W" which is cushioned by the envelop 'V and is held in place against the shoulder U by the similar threaded holding nut Z; the fuel passes thence through the channel P and hole T in the threaded nut t) to the inner nozzle' member ll. Access to the parts of this type of construction is afforded y removing the threadedplugs Y and Yit the bottom ot the earbureter shell. Through the space which separates the'boftom et the 'threaded nut Z and the top (ill the plug Y gasolene is drawn from the lower channel N and passes through the calibrated opening' in the' disk or washer "di into its nozil-claimwl. carburetor nozzle, having, in combination with the apertured carburetor wall, a tubular member having a flanged end engaging therethrough, a washer member pro vided with a` calibrated aperture engaging across the flanged end otsaid tubular member, a peripherally overengaging inelosure for said washer. and means Vlor forcing said 'asher member and its inclosure against the flanged end ot said tubular member. thereby Vforcing the same against the inner face of the carbureter wall.

2. ln a carbureter, an apertured shell, a, terminally flanged tube extending thereinto, a perforated disk located adjacent the inner 4 screw-tln-eadtal portion oi end of said tube, a peripherally arranged cushion tor said disk, and means for holding said disk and its cushion in desired relation to the end ot' saifrl tube and for adjustably forcing the flangedl portion of said tube against those portions of the shell which surround the aperture therein.

ln a rarburoter nozzle, in combination with a terminally flanged tube adapted to project through the earbureter wall, a perforated disk located interiorly of the flanged inner end olt the tube, a peripheral washer Jfor said disk provided with an interiorly extending collar, and a nut adapted to force said disk and its washe against the flange on said tube, thereby 'forcing the flanged portion of said tube firmly against the inner tace of the carburetor wall.

l. ln combination with a threaded and apertured portion of a carburetor -shell, a flanged tube projecting through the aperture with its flanged portion inside of the earbureter shell, a perforated disk, a peripheral envelop therefor located adjacent said flanged portion ot the tube, and a centrally apertured nut adapted to engage the threaded portion of the e-arbureter shell. to force the disk and its envelop toward thef'langed end of the tube, the tlanged jun-tion of the tube thus held in desired tirin relation to the carburetor shell.

5. lu a carburetor, the combination of a shell provided with inlet and outlet apertures, a perforated disk member adapted to regulate the flow through the outlet aper* ture, a iieripheral cushion member therefor, and adjustable means for holding said disk member and its cushion in close relation to said outlet aperture.

f3. In a earbureter, in combination with au apertured shell, a terminally flanged tubular outlet member extending thereinto, with its flaiiged portion in envfayement with the inner tace of the shell af arent the aperture, a disk member provided with a calibrated aperture located across the inner end of said tubular outletmeinber, a periphcrally engaging envelop member hiaetor. and an adjustable nut engaging a correspondingly the shell. whereby said disk men'iber and its envelop are held in close relation to t adjacent tlanged end of said tubular inemi' r, thereby holding` the same firmly against the adjaeenf inner face ot' the shell.

7. ln a. carl'iureter. the combination of an apertured shell, a tlanged tube projecting therethrough, a perforated disk provided with a relatively soft peripheral envelop engaging the flange on said tube, and adjust able 'means for forcing the disk and flanged tube into close relation with respect to the aperture in the shell.
